SNMP Configuration
The Simple Network Management Protocol (SNMP) is a network management standard widely used on UDP networks. It uses a central computer (a network management station) that runs network management software to manage network elements. Three SNMP versions are available: SNMPv1, SNMPv2c, and SNMPv3. Select one or more versions if needed.
Context
- After an NMS accesses a device from the admin-VS through SNMP, the NMS can access non-admin-VSs by carrying the VSID in the community (SNMPv1/v2c) or context (SNMPv3) field of packets. If the NMS accesses a non-admin-VS from the admin-VS, the NMS is authenticated only in the non-admin-VS. For example, if community is set to public123 for the admin-VS, the NMS can use public123@vs=1 (1 indicates the VSID) to access the VSI.
- An NMS cannot access a non-admin-VS from another non-admin-VS.
- Overview of SNMP
- The NMS performs Get and Set operations on a managed device that runs the SNMP agent to manage objects. These objects are uniquely identified in the Management Information Base (MIB).
- Configuring a Device to Communicate with an NMS Using SNMPv1
- After SNMPv1 is configured, a managed device and an NMS can run SNMPv1 to communicate with each other. To ensure communication, you need to configure the agent and NMS. This section only describes the configuration on a managed device (the agent side). For details about configurations on an NMS, see the NMS operation guide.
- Configuring a Device to Communicate with an NMS Using SNMPv2c
- After SNMPv2c is configured, a managed device and an NMS can run SNMPv2c to communicate with each other. To ensure communication, you need to configure the agent and NMS. This section only describes the configuration on a managed device (the agent side). For details about configurations on an NMS, see the pertaining NMS operation guide.
- Configuring a Device to Communicate with an NMS Using SNMPv3 USM User
- After SNMPv3 is configured, a managed device and an NMS can run SNMPv3 to communicate with each other. To ensure communication, you need to configure the agent and NMS. This section only describes the configuration on a managed device (the agent side). For details about configurations on an NMS, see the NMS operation guide.
- Configuring a Local SNMPv3 User on a Device to Communicate with an NMS
- After SNMPv3 is configured, a managed device and an NMS can run SNMPv3 to communicate with each other. To ensure communication, you need to configure the agent and NMS. This section only describes the configuration on a managed device (the agent side). For details about configurations on an NMS, see the NMS operation guide.
